一般疑问句:Be(am, is, are) +主语+现在分词+其它

We were having supper when Tom came in.我们正在吃晚饭时电话响了。(从句表示时间点)

He was cleaning his car while I was cooking. 他洗车时我在做饭。

止性动词,也可以是延续性动词
while只指一段时间。
while从句中的动词必须是延续性动词。
②when说明从句的动作和主句的动作可以是同时,也可以是先后
生;while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。
③when引导的时间状语从句。
后用一般过去时。
While后面一般用过去进行
时。
如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用
while引导,
a.When the teacher came in, we were talking. =While we wer
e talking, the teacher came in.
were singing while we were dancing.

五、现在完成时:
概念:过去发生或已经完成的动作对现在造成的影响或结果,或从过去已经开始,持续到现在的动作或状态。
(一)构成:主语+have/has+V过去分词。
“have /has”如何使用需记清。
当主语是I,you和复数名词或代词时要用have;单数主语后跟has。
也就是说have/has需同主语的人称或数保持一致。
(二)用法
接触一:肯定句式
现在完成时的肯定句式是“have(has)+过去分词”。
如:
① We have just finished our homework.② She has gone home.
注意:1)该句式中的have或has是助动词,has用于第三人称单数,其它人称一律用have。
2)该句式中have(has)和过去分词之间可用just插入。
3)把该句式译成汉语时,往往用“已经”、“刚刚”、“过”或“了”等。
接触二:疑问句式
现在完成时的一般疑问句式是把助动词have或has提到主语之前。
如:
③ Have you read this story book yet
特殊疑问句及反意疑问句结构如下:
④ What have you done with my bike
⑤ You've read this story book, haven't you
注意:1)现在完成时的一般疑问句往往在句末加yet。
2)把现在完成时的一般疑问句译成汉语时,往往译成“……过吗”、“已经……了吗”等。
3)其肯定回答用“Yes,...have(has).”,否定回答用“No,...haven't(hasn't).”,有时用“No,not yet.”或“No,never.”。
接触三:否定句式:现在完成时的否定句式是“haven't(hasn't)+过去分词”。
如:
⑥ We haven't studied Unit 2 yet.⑦ The train hasn't stopped yet.
注意:1)现在完成时的否定句句末往往加yet。
2)否定句常译为“还没有……”等。
接触四:用法之一:现在完成时表示过去发生或完成的某一动作对现在造成的影
响或结果。
如:
Have you read that story你读过那个故事吗
(“读”这一动作发生在过去,对现在造成的影响是:是否知道故事的内容。
)
I have bought two apples.我买了两个苹果。
(“买”这一动作发生在过去,对现在造成的结果是:拥有两个苹果。
)
在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already,just,ever,yet,never等。
already,just多用于肯定句中,ever,yet,
never多用于疑问句和否定句中。
如:
I have already finished my homework.我已经做完家庭作业了。
He has just had his meal.他刚吃过饭。
Have you ever sung this English song你曾唱过这首英文歌吗
They haven't started yet.他们还没有动身。
We have never heard of it.我们从来没有听说过这件事。
接触五:用法之二 :表示过去已经开始,一直持续到现在的动作或状态。
注:这一用法即现在完成进行时的用法
因为表示的是持续的动作或状态,所以使用的动词通常是延续性动词:be, stay, study, wait, keep, have… 等;
使用的时间状语通常由for或since 引导,但二者后接的词有所不同:
for后常跟一个时间段,指某个动作到现在为止已持续了多长时间,如for three years, for half an hour等。
since 作介词,后面可以接一个时间点,如since 1980,也可以接“一段时间+ago”,
如: since three years ago, since two months ago等。
since 还可用作连词,引导一个过去时态的时间状语从句。
如:We have known each other since we went to college.
非延续性动词不能直接和for 或since 连用,但我们可以找一个相应的延续性动词或动词短语来替换这些非延续性动词,如: come→be, come to→be in / at, go out→ be out, leave→be away, begin / start→be on, stop→ be over,buy→ have, borrow→ keep, open→be open, close→be closed,
join→be a member of, die→be dead, catch a cold→have a cold, get to know→know, become a teacher →be a teacher, fall asleep→be asleep, fall ill→ be ill等。
句型It is the first (second, third...) time that...的that从句中,谓语动词须用现在完成时,表示到说话时为止动作发生过几次。
如:It is the first time that I have been here.
接触六:现在完成时与一般过去时的用法比较
现在完成时表示过去的动作对现在造成的影响;一般过去时表示动作发生的时间在过去。
试比较:
The plane has arrived . 飞机已经来了。
(说明现在的情况:飞机在这儿。
)
The plane arrived a quarter of an hour ago. 飞机是一刻钟以前抵达的。
(强调动作发生的时间在过去。
)
接触七:have been in, have been to 与have gone to 的用法
1. have(has) been in 意为“已经在某地呆了多长时间”,常与表示一段时间的状语连用。
如:
Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了。
They have been in Canada for five years. 他们到加拿大有五年了。
2. have(has) been to意为“曾经去过某地”,表示现在已经不在那里了。
可与just, ever, never等连用。
如:

接触八:常用于现在完成时的时间状语
除了我们讲过的already, yet, still,just, ever, never, since短语和 for 短语外,还有许多时间
状语常用于现在完成时,我们要留心将它们和一般过去时的时间状语区分开来:1. lately, recently是完成时的时间状语;just now 有a moment ago 之意,是过去时的时间状语。
如:
Have you heard from your family lately/recently Did you see Joan just now
2. in the past few years 意思是“过去几年来”,常用于完成时中;
in the past意思是“在过去”,常用于过去时中。
如:
Great changes have taken place in my hometown in the past few years. Where did you work in the past
3. ever since then与from then on / after that 都有“打那以后”之意,但前者常用于完成时,而后两者常用于过去时。
如:
She\'s lived here ever since then. I didn\'t hear of Jim from then on/after that.
4. before 通常用于完成时;...ago通常用于过去时。
如:
I have never been to Japan before. She went to Japan two years ago. 5. so far“到目前为止”,these days“这些天来”也是现在完成时常见的时间状语。
如:
So far, no man has travelled farther than the moon. What have you done these days

④特殊疑问句:特殊疑问词或词组+一般疑问句(Had+主语+过去分词)
基本用法
(1)表示在过去某一时刻或动作以前完成了的动作,也可以说过去的时间关于过去的动作。
即“过去的过去”。
可以用by, before等介词短语或一个时间状语从句来表示,也可以用一个表示过去的动作来表示,还可能通过上下文来表示。
By nine o’clock last night, we had got 200 pictures from the spaceship. 到昨晚9点钟,我们已经收到200 张飞船发来的图片。
(2)表示由过去的某一时刻开始,一直延续到过去另一时间的动作或状态,常和for, since构成的时间状语连用。
I had been at the bus stop for 20 minutes when a bus finally came. 当车来的时候,我在车站已等了20分钟。
He said he had worked in that factory since 1949. 他说自从1949年以来他就在那家工厂工作。
(3)叙述过去发生的事情,在已叙述了过去发生的事情后,反过来追述或补述以前发生的动作时,常使用过去完成时。
Mr. Smith died yesterday. He had been a good friend of mine. 史密斯先生昨天去世了。
他以前是我的好友。
I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知,因为我没有好好学习功课。

I returned the book that I had borrowed. 我已归还了我借的书。
She found the key that she had lost. 她丢失的钥匙找到了。
(5)过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句(或间接引语)中,这时从句中的动作发生在主句表示的过去的动作之前。
He said that he had known her well. 他说他很熟悉她。
I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。
(6)状语从句:在过去不同时间发生的两个动作中,发生在前,用过去完成时;发生在后,用一般过去时。
如when,before,after,as soon as,till/until 引导的
When I woke up, it had already stopped raining. 我醒来时雨已停了。
She didn’t go to bed until she had finished her work.她直到把工作做完之后才睡觉。
